About Kaipen
Kaipen is a much-loved snack from Laos, made from crispy sheets of edible algae harvested from the country’s rivers. Far more than just a treat, these chips offer a wholesome alternative to conventional crisps and are prized for their savoury, umami-rich flavour. They are often served with aromatic dips that round out the taste beautifully. The interplay of salty and spicy notes tempts the palate and draws you deep into the exotic cuisine of Laos.
Ingredients (serves 1–2)
- 100 g algae (e.g. nori or other edible seaweed)
- 2 tablespoons fish sauce, or soy sauce for a vegan version
- 1 teaspoon chilli powder, or freshly chopped chilli
- 1 tablespoon sesame oil
- A squeeze of lime juice
Shopping for the ingredients
The fresh ingredients for Kaipen are available in most Asian supermarkets or well-stocked grocery shops. The choice of algae may vary with the season, but you can usually find nori or wakame. Take care to pick the right fish sauce — or its vegan alternative — to get the best possible flavour. The remaining ingredients, such as sesame oil and lime juice, are easy to find in any regular supermarket.
Preparing the dish
Preparing Kaipen does not take much time and is straightforward to do. Begin by cutting the algae into smaller pieces so they are easier to work with. The marinade is made from the fish sauce, the chilli powder, the sesame oil and the lime juice. Dip the algae into the marinade so they can soak up all those delicious aromas.
Step-by-step instructions
- Cut the algae into small pieces.
- Stir together the marinade of fish sauce, sesame oil, chilli powder and lime juice.
- Dip the algae into the marinade and mix thoroughly.
- Lay the marinated algae out on a baking tray.
- Bake in a preheated oven at 180°C for about 10–15 minutes, until crisp.
Gluten-free / lactose-free version
For a gluten-free version, you can use a gluten-free soy sauce in place of the fish sauce. When choosing your algae, it is important to check that they do not contain any gluten-based additives. The rest of the process stays exactly the same, and you can still look forward to a delicious result. As for a lactose-free version, the ingredients used here are naturally lactose-free, so no further adjustments are needed.
Tips for vegans and vegetarians
Vegans can prepare Kaipen with ease by swapping the fish sauce for a plant-based alternative such as soy sauce or tamari. Make sure the algae and all the other ingredients are free of animal products. These crispy algae chips are therefore perfect for anyone following a plant-based diet. Enjoy them as a snack or as part of a dip spread with fresh vegetables — much like the fresh, crunchy appeal of a Som Tam.
More tips and tricks
Another good tip is to keep an eye on the baking time to avoid over-browning the algae. If you like things extra flavourful, scatter over some sesame seeds or roasted peanuts before baking. Experiment with different spices in the marinade to add your own personal touch. Kaipen is wonderfully adaptable and can be tweaked to suit your taste, in the same spirit as the fiery Jeow Bong relish.
Adapting the recipe to your taste
If you prefer a milder version, you can reduce the amount of chilli or leave it out altogether. Many people also swear by a touch of sweetness, adding a little honey or agave syrup to the marinade. When making Kaipen, you have plenty of room to get creative and adjust the dish to your individual preferences. That way you create a fresh taste experience every single time!
Ingredient substitutions
If you are not keen on algae, you can instead use thinly sliced vegetables such as courgette or carrot to make crispy chips. A blend of different spices — paprika or garlic powder, for example — can also bring an exciting change. The basic principle stays the same: treat the ingredients much as you would the algae. In this way you create “chip” variations that impress just as much, pairing well with a hearty Larb.
Drink pairing ideas
Kaipen goes wonderfully with refreshing drinks such as green tea or fruit juices. A dry white wine or a fruity cocktail also harmonises perfectly with the salty, spicy notes. Try a homemade lemonade with fresh mint leaves for a refreshing treat. The choice of drinks should always support and round out the flavour of the chips.
Serving and presentation ideas
Presenting Kaipen attractively is simple. Serve the chips in a lovely bowl and garnish with fresh herbs or edible flowers. You can also arrange the dips in small portions alongside to create an appealing look. This gives the dish not only an attractive appearance but also an inviting atmosphere for your guests.
A bit of history
Kaipen has its roots in traditional Laotian cuisine, where food preparation and preservation play a central role. Algae are an important part of the diet in many Asian cultures, thanks to their rich nutritional value. In Laos, this snack has become a much-loved finger food, often enjoyed by locals at social gatherings. Its uncomplicated preparation and versatility make Kaipen a timeless snack, cherished both locally and internationally — a fine example of Laotian cuisine.
